What was the earliest you could feel any BH contractions? I'm almost 26 weeks and I feel like my body is well & truly priming itself which is very unsettling to say the least. With my first pregnancy I got absolutely nothing until I was in labour at 39 weeks.

I am definitely getting tightenings of some description, its more like waves of sensation right down low. It will happen regularly for up to an hour or so, then go away and I won't feel it for a few more hours or until the next day.

Any thoughts?
